Thanks to CTOnews.com netizens Aurora Meteor and sauerkraut students for their clue delivery! CTOnews.com December 11 news, Xiaomi 13 series & MIUI 14 new product launch will be held at 19:00 today. At that time, the new Xiaomi 13 series of mobile phones will be officially unveiled.

Xiaomi mobile phone official interpretation of Xiaomi 13 battery technology at noon today, said that the small size of the fuselage to have a long range, battery technology innovation is the only way out, high silicon negative battery + MCP battery packaging technology, in the same volume to increase battery power to increase 260mAh, so that Xiaomi 13 battery life up to 1.37days, "become the millet digital series of the most".

Xiaomi said that as a member of the two-size flagship strategy, Xiaomi 13 carries the banner of a small-size flagship. In order to carry the newly upgraded Leica three-camera system and completely innovative performance in a small size fuselage, the only stacking space left for the battery is the 24.744cm3, which is 5.4% smaller than the already small space of the previous generation of Xiaomi 12, which can only hold 4240mAh batteries if designed according to the previous generation of batteries.

According to reports, in the internal evaluation, the battery life of the 4240mAh has greatly exceeded that of the previous generation, but 4500mAh capacity has become a hard threshold for smartphones. The only way to achieve a satisfactory balance between volume and capacity is to increase the energy density of the battery.

When talking about how to increase the energy density of the battery, Xiaomi said the core is how to de-intercalate more lithium ions. The battery carried on Xiaomi 13 is precisely the crystallization of the "high silicon and lithium supplement" of power battery technology. Xiaomi 13 tripled the proportion of silicon added to the original negative electrode to obtain a higher energy density, and it is estimated that the battery capacity of the high silicon negative electrode technology is equivalent to an increase in 200mAh.

CTOnews.com learned that Xiaomi pointed out that this battery of Xiaomi 13, with a fast charging capacity of 67W, has an energy density as high as 735Wh / L, making it the king of energy density among fast-charging batteries of the same power. At the same time, the problems of high expansion and cyclic attenuation which are gradually magnified with the increase of silicon ratio are solved through the design of porous structure.

In addition, Xiaomi said that the MCP packaging technology was used for the first time on the Xiaomi 13 battery, and the original protection circuit module was tiled in the fuselage, which would take up more space. Now through the accurate positioning of the top seal on the top of the battery and strictly controlling the bending angle, the whole protection circuit module can be changed from flat to upright, from the direction of battery length to the direction of thickness, so as to realize three-dimensional stacking. This reduces the stack space of the battery head by 20%, and the capacity is equivalent to 60mAh. Through the high silicon negative electrode technology and MCP highly integrated packaging, the original space can only hold 4240mAh battery capacity to supplement to 4500mAh, the core purpose is only one, is to reduce the size of the battery, while ensuring capacity life, at the same time for other parts can make more space.

According to previous information, the Xiaomi 13 has a slightly 2.5D front, a four-curved back, a 71.5mm width, the latest second-generation Snapdragon 8 flagship processor, LPDDR5X memory and UFS 4.0 flash memory. In terms of image, Xiaomi 13 is equipped with Leica 75mm humanities telephoto lens and f / 2.0 super aperture.
